Ritual Repetition stands as one of the most densely theorized concepts in the depth-psychology corpus, commanding sustained attention from historians of religion, analytical psychologists, mythologists, and anthropologists alike. Mircea Eliade provides the conceptual foundation: ritual repetition is not mere behavioural recurrence but the deliberate re-enactment of a cosmogonic or divine archetype, collapsing profane time and restoring the sacred illud tempus of origins. Every consecration, sacrifice, or festival ceremony re-performs a primordial act, thereby lending existence its ontological validity. Jung inherits this framework but reframes it: ritual repetition counteracts psychic regression within groups, anchoring the individual in symbolic experience rather than mass unconsciousness. Hillman introduces a provocative alchemical inflection, reading iteratio — the complaint ‘yet again’ — as the very essence of ritual, a sacrificial circulatio that refines psychic substance through enforced return. Burkert grounds repetition in a biological-evolutionary register, arguing that stereotyped, repeated behavioral patterns constitute the communicative core of all ritual from graylag geese to Greek sacrifice. Campbell traces how mythological re-enactment structures initiatory transformation across cultures. These positions share a conviction that repetition is not regressive but regenerative — the mechanism by which the soul, the community, and the cosmos are periodically reconstituted. The central tension is whether repetition derives its power from external cosmic archetype, internal psychic structure, or adaptive group function.
